The Army is calling those burns a success and the plans to move forward and detonate munitions on the base are now in the works.

The Army still has 3,000 acres left to burn on the site. Ed Walker, from the Department of Toxic Substance Control, said, although there's no timeline, they're making steady progress.

"It will probably take a few months. I think it's up to a little over 900 acres, so it's a fairly large area and depending on how it goes, it may be once they get in there, they can complete it in a set amount of time," Walker said.

After a mandatory cool down period, the Army will access the burn units and then proceed with detonating munitions left over from the days when Fort Ord was an active military base.

It's a lengthy process that's costing taxpayers $100 million. The entire project is slated for completion in eight to 10 years.
